Polyvinyl chloride ua cov roj nplua nyeem tau muab faib ua cov roj nplaum sab hauv thiab cov roj ntsha sab nraud. Txhim kho qhov fluidity ntawm PVC yaj, tiv thaiv cov khoom los ntawm kev ua raws li cov khoom siv, txhim kho lub zog ntawm cov khoom siv, thiab txhim kho kev ua haujlwm ntawm cov khoom.
Lub lubricant zoo tshaj plaws yuav tsum muaj kev ua haujlwm zoo lubrication, tuaj yeem txhim kho lub ntsej muag gloss, pob tshab lossis adhesion tsis kam ntawm cov khoom, kom cov khoom muaj hluav taws xob zoo thiab cov khoom siv kho tshuab.
Feem ntau siv PVC lubricants muaj xws li fatty acids thiab hlau soaps, esters, amides, hydrocarbons, thiab lwm yam. Lubricant yog tsuas yog siv rau zus tau tej cov PVC khoom nyuaj, tus nqi ntawm txog 20, 000 t / a. Txoj kev loj hlob ntawm lubricants yog los tsim cov khoom sib xyaw tsim nyog rau kev ua haujlwm siab thiab kub siab, uas muaj cov yam ntxwv zoo, tsis muaj plua plav thiab tsis muaj tshuaj lom.
Thaum tshav kub kub stabilizers tuaj yeem txhim kho qhov tsis ruaj khov ntawm PVC nws tus kheej, thiab cov roj nplua nyeem tuaj yeem txhim kho cov dej ntws ntawm PVC yaj thiab txo cov adhesion. Tsis tas li ntawd, PVC additives kuj muaj xws li plasticizers, tej yam kuj, nplaim retardants, lubricants, tshuab tshuab, lub teeb stabilizers, anti-fogging agents thiab lwm yam additives. Tam sim no, cov khoom siv hauv tsev PVC yog ib leeg, cov khoom lag luam qib qis, thiab qhov sib txawv yog loj nrog cov teb chaws txawv teb chaws, uas tsis tuaj yeem ua tau raws li cov kev xav tau zoo ntawm cov khoom siv hauv tsev PVC, thiab xav tau kev txhim kho thiab txhim kho ntxiv.
